Claims
- 1. A method of monitoring data regarding continuously varying injection pressure in an injection process of an injection molding machine comprising the steps of: detecting data regarding the injection pressure as a variable of time using multipoint sampling for one injection operation cycle of said machine, storing detected data of said one injection operation cycle as reference data, detecting data regarding the injection pressure as a variable of time using multipoint sampling for another injection operation cycle of said machine, comparing said stored reference data with said detected data regarding the injection pressure in said another injection operation cycle, and generating an alarm information when a deviation between said detected data for said another operation cycle and said reference data exceeds a predetermined limit.
- 2. The method according to claim 1 wherein generation of the alarm information is stopped for a predetermined time interval during a data sampling time.
- 3. The method according to claim 2 wherein said predetermined time interval in which the generation of the alarm information is stopped, starts from a starting time of the injection process of the injection molding machine.
